FIG. 1 is a top-front, right side perspective view of an instrument for measuring optical wave front showing my new design;

FIG. 2 is an top-front, left side perspective view thereof;

FIG. 3 is a bottom-front, right side perspective view thereof;

FIG. 4 is a top-back, right side perspective view thereof;

FIG. 5 is a top-back, left side perspective view thereof;

FIG. 6 is a right side elevational view thereof;

FIG. 7 is a front elevational view thereof;

FIG. 8 is a left side elevational view thereof; and,

FIG. 9 is a back elevational view thereof.

The submitted line drawings (FIGS. 1-9) show some additional solid lines on the instrument for measuring optical wave front, which, as is generally recognized by persons skilled in the art, are meant to convey shading or the boundaries for curved surfaces on the device, and are not meant to convey actual solidly drawn lines for actual surface markings or ornamentation.

In the drawings, the broken lines are for the purpose of illustrating environment only and form no part of the claimed design. 

CLAIM The ornamental design for an instrument for measuring optical wave front, as shown and described.
